To @ZZ whom t may concern.'

Be it known thatI I, WILLIAM J BROWN, a citizen of the United States of America, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Wall- Paper Removing Machines, of which the following is a specification.

This invention relates to wall paper removing machines, and has for its object to provide a machine of such class, in a manner as hereinafter set forth, which is capable of being shifted over a wall for splitting the paper thereon and then scraping it therefrom, thereby cleaning the wall of the paper.

A further object of the invention isv to provide a wall paper removing machine,I in a manner as hereinafter set forth, having a scraping knife and a guide associated with said knife, said guide preventing the knife from entering deeply into the plaster-wall,

. during the operation of removing the paper drawings, wherein is shown an embodiment of the invention,`but it is to be understood that changes, Avariations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

`Figure 1 is a longitudinal sectional view on line I--I, Fig. 2, of a wall paper removing machine in accordance with this invention.

Fig. 2 is a sectional plan, line II-II, Fig. 1. y

, Fig. 3, is a side elevation of the machine.

Fig. 4 a front view.

Fig. 5 an elevation of the scraping knife.

Fig. 6 a perspective view of one of the splitting knives.

Referring to the drawings in detail the machine comprises a frame consisting of a The side members 1,2, near their rear l ends, are provided with inwardly extending bearings 6, 7, for a transverse axle 8, carrying a pair of wheels 9, which are arranged within the frame and depend slightly below the bottom thereof. The axle gear 10.

Supported by the plate 3, is an electric motor 11, theshaft 12, of which projects rearwardly and forwardly therefrom. The rear end of the shaft 12, carries a bevel gear 13, which meshes with thebevel gear 10, the latter being of materially greater diameterV than the bevel gear 13. The reference character 14, denotes leading-in-wires for the motor 11. s v The plate 3, forwardly of the motor 11, is formed with a hollow standard 15, which provides a bearing for the shaft 16, projecting from the hub 17, of a bevel gear wheel 8, has a bevel 18. The hub 17, is seated upon the standard 15. A y The forward end of the shaft 12, is provided with'a bevel gear 19, which meshes witha bevel gear 18. i I

The end member 5, at its lower end has an inclined slot 20, and above said slot is ing through' lthe openings 21, and also through the apertured upper ends of fixed standards 25", which are secured to the bottom plate 3, at each side of the gear 18.

The gear has a pin 26a, to which is pivotally connected a lever arm 27, they latter being pivotally connected to the carrier 26, as at 28.

Adjustably mounted upon the end member 5, as well as having its lower end projecting forwardly of the knife 23, is a yoke shapedgoverning member 29', the latter being adj ustablyconnected tothe end member 5, as at 30. The lower portion of the governing member 29, which projects forwardly from the end member 5, consists of a pair of 't guide bars 3l, 32, which are l:spacedapart to 34, 35, and a part of saidvslot 33', is" always positioned forwardly of the extreme limit of the outward stroke of the knife' 23. The bar 32 is arranged in advance of the knife 23. Connected to each end of the bar 32 1s a splitting knife 35, which isslotted as 'at 36,l and they latter in connection with the Screw 3:71,. provides means for adinstably connecting the splitting knife 3,5',4 in po.- sition. The splitting knife 3 5, connection with the bar 32, travels forwardly of the scraping knife 23, and will prevent the latter from entering the plaster wall tOo deeply, when traveling over an. uneven Wall surface, under such conditions governing the scraping stroke of the knife 23.

The motorA ll, is Ilot. only employed for propelling; the machine over the wall,v but also for operating the knife. v

Hinged o the, member 2, as at. 38,15 a lid or cover 39, which when closed is seated upon ribs 40 projecting inwardly from the end members 4;, 5. The lid orcover 39, is detaehably connected as at.. 4l, t0 vthe slde member 1L A. flexible handle 42, is provi.ded and is secured at one encas at e3, te the cover 39, and atA its other end as at 44 to the side member 2..` The leading in wires 14C,v extend; outwardly through the end member 4l.

The knives, 35, are employed'v for splitting the.. .apen prier te the scraping of the same olf he wall by the knife 23, and understtch conditions the: paper removing ope-ration will be ezqoedgi-kzed.4 The paper scraped from the wall by the knife 23, is; caused to pass, .upf through the slot 33,.as illn: st;rat ed,A

by Flg 1 A suitable switch may be employed .fr-

opening and closing the 'electrical circuit for eentrellin-g the. operation. of the neo` tor 11;.
